Ultrasonic sanitation device and associated methods

Abstract

A device for sanitizing a space includes a tank having an interior space for holding an aqueous sanitizing liquid. A reactor vessel is supported within the interior space and above a bottom of the tank. A liquid depth in the tank interior space is maintained at a level beneath a top edge of the reactor vessel. An ultrasonic head comprising an ultrasonically vibratable disc for generating ultrasonic energy is positionable within and beneath the top edge of the reactor vessel. Liquid is transferrable from the tank interior space to the reactor vessel to a level for substantially submerging the ultrasonic head. The disc is vibrated to form an atomized fog of particles from the aqueous sanitizing liquid. The formed atomized fog is exhausted from the reactor vessel to a space exterior of the tank. A sanitizing composition is also provided.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to systems and methods for sanitizing enclosed spaces, and, more particularly, to such systems and methods that are capable of treating spaces three-dimensionally.[0003]2. Description of Related Art[0004]The sanitization and disinfection of enclosed spaces has become an issue of increasing importance owing to the possible presence of both natural and deliberately introduced contaminants. Since most commercial buildings are “sealed,” that is, their windows cannot be opened, circulation of “fresh” air is typically not possible within a particular room. Similarly, most houses are now effectively sealed, with mostly processed air being circulated. In addition, some forms of conveyance, especially airplanes, are of necessity sealed against the environment during flight.[0005]The enclosed nature of modern spaces has led to such problems as “sick building syndrome,” since molds and mildews can flo...

AI Technical Summary

Benefits of technology

"The present invention is a device that sanitizes a space by using an aqueous sanitizing liquid and an ultrasonic head to create an atomized fog. The device can be used to distribute the liquid to different areas in a space. The atomized fog has been found to remain airborne longer than conventional mists, making treatment more thorough and requiring less chemical. The device can disinfect a room in 10 min or less. The invention has the advantage of being able to reach all areas in a space where air can penetrate."

Problems solved by technology

The sanitization and disinfection of enclosed spaces has become an issue of increasing importance owing to the possible presence of both natural and deliberately introduced contaminants.

Since most commercial buildings are “sealed,” that is, their windows cannot be opened, circulation of “fresh” air is typically not possible within a particular room.

The enclosed nature of modern spaces has led to such problems as “sick building syndrome,” since molds and mildews can flourish in enclosed, damp environments, and also to the possibility of the deliberate introduction of more insidious threats to life, such as biological and chemical agents.
